A reliable fish list tied specifically to Treasure Bayou is difficult to verify, which makes it smarter to carry simple freshwater gear until the fishery is clearer, so I would treat the first outing as a chance to identify the main targets. I would start with a simple freshwater kit with a small soft plastic and a live-bait option, because if something starts biting, the rest of the trip can be built around that clue.
On Treasure Bayou, I would begin around one sheltered section of bank and keep the first plan simple; a slow start is a reason to make one thoughtful change rather than rebuild the entire tackle plan.
